We will make Vesper for iOS, Vesper for Mac, and Vesper’s JavaScript sync service open source on my personal GitHub account. This code will also be provided as historical artifacts: they’re not intended as active projects. They’re also not intended as examples of how to write apps these days.
I applaud the team’s decisions to open source the Vesper code base, especially the syncing component that Brent put so much work into. Perhaps, like the ill-fated Letters.app, Vesper’s demise will give way to new applications that may fare better.
